No sure if this counts but I'm an original owner form the early 90's however I'm on my 3rd NSX now.
I do know a guy that is also an original owner from 1991, purchased his car new at the launch of the NSX at the London motor show back then, and was one of the first owners of an NSX here in Ireland and kept it for many many years [I think 15 years], he's now on his 2nd NSX.
